Hi, I have been able to resolve the problem. In order to use sub-process in jbpm-jpdl-3.2.1, you should change the jbpm.cfg.xml in jbpm-console.war to include the customised bean class. If you include the following: <bean name="jbpm.sub.process.resolver" class="org.jbpm.custom.DbSubProcessResolver" /> in your jbpm.cfg.xml and build the war file again, I hope you can then successfully deploy and create a process instance which in turn makes a cal to a sub-process. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059601#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
